ASP.net Javascript

Hi Coders I need a solution for the following scenario in VB.net. I have a sub in codebehind which I need to call from a Javascript confirm box. Forexample : I have a two form fields: txtBox1 and txtBox2 and a button. Now if the user hits submit button it should show the Javascript Confirm box. which is fine then I need if the user selects yes then it should call another sub which updates the data otherwise it gets cancel and updates only one txtBox field. any suggestions or solution is welcome. thanks anfd kind regards ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Exclusive and complete copyrights to all work purchased.
